Missed verbatim. Thanks for the pointer, it works, but i think that
perl is double-processing returned values. If we do the same things in
elisp i get (my) expected results:

#+begin_src elisp :results raw
  "|c1|c2|
  |-
  |a|1|
  |b|2|";
#+end_src

#+results:
| c1 | c2 |
|----+----|
| a  |  1 |
| b  |  2 |

*NOTE* this will not properly clean-up the results, but keep inserting
more copies.
#+begin_src elisp :results raw verbatim
  "|c1|c2|
  |-
  |a|1|
  |b|2|";
#+end_src

#+results:
"|c1|c2|
|-
|a|1|
|b|2|"

Yes, this was included to show the inconsistency between value and
output returns. BTW, "raw output" and  "raw output verbatim" generate
the same results.

I will take a look and see if i come up with anything else. In
general, what I have found with babel processing is that there is
major inconsistency between the results processing in different
languages. Somehow, I would think that the same  output (modulo
sytnactic diferences) should generate the same results regardless of
language.
